SUMMARY

Disclosed herein are engineered oligonucleotides or salts thereof that can comprise a polynucleotide sequence. In some embodiments, an engineered oligonucleotide or salt thereof can be at least partially complementary to at least a portion of at least a first and a second RNA originating from two genetic loci that are associated with a disease or condition. In some embodiments, when an engineered oligonucleotide or salt thereof at least partially binds to a first RNA: a first region of at least seven contiguous bases in the engineered oligonucleotide can be complementary to contiguous nucleic acids contained within the first RNA and a second region of at least five contiguous bases in the engineered oligonucleotide can be complementary to contiguous nucleic acids contained within the first RNA. In some embodiments, when an engineered oligonucleotide or salt thereof at least partially binds to a second RNA: a first region of at least seven contiguous bases in the engineered oligonucleotide can be complementary to contiguous nucleotides contained within a second RNA, and a second region of at least five contiguous bases in the engineered oligonucleotide can be complementary to contiguous nucleotides contained within the second RNA. In some embodiments, a predicted Gibbs free energy (ΔG) of binding of an engineered oligonucleotide to a first and a second RNA can range, individually, from about −17 to about −36 kcal mol⁻¹ at about 37 degrees Celsius and at a pH ranging from about 7.2 to about 7.6. In some embodiments, an engineered oligonucleotide or salt thereof can be an antisense oligonucleotide, a synthetic microRNA (miRNA), or a small interfering RNA (siRNA). In some embodiments, an engineered oligonucleotide or salt thereof can comprise one or more nucleotide insertions, nucleotide deletions, nucleotide substitutions, or any combination thereof, relative to one or more otherwise comparable non-coding RNAs (ncRNAs). In some embodiments, an engineered oligonucleotide or salt thereof, when at least partially bound to the first or the second RNA, can have an at least about 10% lower Gibbs free energy (ΔG) of binding at about 37 degrees Celsius and at a pH ranging from about 7.2 to about 7.6, relative to a ΔG of binding of the otherwise comparable ncRNA binding to the first or the second RNA at about 37 degrees Celsius and at a pH ranging from about 7.2 to about 7.6. In some embodiments, an engineered oligonucleotide or salt thereof can be from about 5 to about 50 nucleotides in length. In some embodiments, an engineered oligonucleotide or salt thereof can comprise a ribose sugar. In some embodiments, an engineered oligonucleotide or salt thereof can comprise a deoxyribose sugar. In some embodiments, an ncRNA can be an miR-30 mircro RNA (miRNA), an miR-29 miRNA, an miR-26 miRNA, an miR-27 miRNA, an miR-101 miRNA, an miR-145 miRNA, an miR-205 miRNA, an miR-338 miRNA, or an miR-375 miRNA.

DETAILED DESCRIPTION Definitions

Unless otherwise indicated, open terms for example “contain,” “containing,” “include,” “including,” and the like mean comprising.

The singular forms “a”, “an”, and “the” are used herein to include plural references unless the context clearly dictates otherwise. Accordingly, unless the contrary is indicated, the numerical parameters set forth in this application are approximations that can vary depending upon the desired properties sought to be obtained.

As used herein, the term “about” or “approximately” can mean within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, e.g., the limitations of the measurement system. For example, “about” can mean plus or minus 10%, per the practice in the art. Alternatively, “about” can mean a range of plus or minus 20%, plus or minus 10%, plus or minus 5%, or plus or minus 1% of a given value. Alternatively, particularly with respect to biological systems or processes, the term can mean within an order of magnitude, within 5-fold, or within 2-fold, of a value. Where particular values are described in the application and claims, unless otherwise stated the term “about” meaning within an acceptable error range for the particular value should be assumed. Also, where ranges and/or subranges of values are provided, the ranges and/or subranges can include the endpoints of the ranges and/or subranges.

The term “substantially” as used herein can refer to a value approaching 100% of a given value. In some cases, the term can refer to an amount that can be at least about 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 99.9%, or 99.99% of a total amount. In some cases, the term can refer to an amount that can be about 100% of a total amount.

The term “homology” can refer to a % identity of a sequence to a reference sequence. As a practical matter, whether any particular sequence can be at least 50%, 60%, 70%, 80%, 85%, 90%, 92%, 95%, 96%, 97%, 98% or 99% identical to any sequence described herein (which can correspond with a particular nucleic acid sequence described herein), such particular polypeptide sequence can be determined conventionally using known computer programs such the Bestfit program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, 575 Science Drive, Madison, Wis. 53711). When using Bestfit or any other sequence alignment program to determine whether a particular sequence is, for instance, 95% identical to a reference sequence, the parameters can be set such that the percentage of identity is calculated over the full length of the reference sequence and that gaps in homology of up to 5% of the total reference sequence are allowed.

For example, in a specific embodiment the identity between a reference sequence (query sequence, i.e., a sequence as described herein) and a subject sequence, also referred to as a global sequence alignment, can be determined using the FASTDB computer program based on the algorithm of Brutlag et al. (Comp. App. Biosci. 6:237-245 (1990)). In some cases, parameters for a particular embodiment in which identity is narrowly construed, used in a FASTDB amino acid alignment, can include: Scoring Scheme=PAM (Percent Accepted Mutations) 0, k-tuple=2, Mismatch Penalty=1, Joining Penalty=20, Randomization Group Length=0, Cutoff Score=1, Window Size=sequence length, Gap Penalty=5, Gap Size Penalty=0.05, Window Size=500 or the length of the subject sequence, whichever is shorter. According to this embodiment, if the subject sequence is shorter than the query sequence due to N- or C-terminal deletions, not because of internal deletions, a manual correction can be made to the results to take into consideration the fact that the FASTDB program does not account for N- and C-terminal truncations of the subject sequence when calculating global percent identity. For subject sequences truncated at the N- and C-termini, relative to the query sequence, the percent identity can be corrected by calculating the number of residues of the query sequence that are lateral to the N- and C-terminal of the subject sequence, which are not matched/aligned with a corresponding subject residue, as a percent of the total bases of the query sequence. A determination of whether a residue is matched/aligned can be determined by results of the FASTDB sequence alignment. This percentage can be then subtracted from the percent identity, calculated by the FASTDB program using the specified parameters, to arrive at a final percent identity score. This final percent identity score can be used for the purposes of this embodiment. In some cases, only residues to the N- and C-termini of the subject sequence, which are not matched/aligned with the query sequence, are considered for the purposes of manually adjusting the percent identity score. That is, only query residue positions outside the farthest N- and C-terminal residues of the subject sequence are considered for this manual correction. For example, a 90 residue subject sequence can be aligned with a 100 residue query sequence to determine percent identity. The deletion occurs at the N-terminus of the subject sequence and therefore, the FASTDB alignment does not show a matching/alignment of the first 10 residues at the N-terminus. The 10 unpaired residues represent 10% of the sequence (number of residues at the N- and C-termini not matched/total number of residues in the query sequence) so 10% is subtracted from the percent identity score calculated by the FASTDB program. If the remaining 90 residues were perfectly matched the final percent identity would be 90%. In another example, a 90 residue subject sequence is compared with a 100 residue query sequence. This time the deletions are internal deletions so there are no residues at the N- or C-termini of the subject sequence which are not matched/aligned with the query. In this case the percent identity calculated by FASTDB is not manually corrected. Once again, only residue positions outside the N- and C-terminal ends of the subject sequence, as displayed in the FASTDB alignment, which are not matched/aligned with the query sequence are manually corrected for.

In some cases, an engineered oligonucleotide or salt thereof can comprise at least about: 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% sequence identity to an oligonucleotide of any SEQ ID NO as described herein. In some cases, an engineered oligonucleotide or salt thereof can comprise at least about: 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% sequence identity to at least 10 contiguous bases of an oligonucleotide of any one of SEQ ID NOs as described herein.

A regulatory non-coding RNA (ncRNA) comprises short non-coding RNA sequences expressed in a genome that regulates expression or function of other biomolecules in mammalian cells. An ncRNA is generally <200 nucleotides in length and can be single stranded or double stranded, and may form non-linear secondary or tertiary structures. An ncRNA can comprise exogenously derived small interfering RNA (siRNA), MicroRNA (miRNA), small nuclear RNA (U-RNA), Small nucleolar RNA (snoRNA), Piwi-interacting RNA (piRNA), repeat associated small interfering RNA (rasiRNA), small rDNA-derived RNA (srRNA), transfer RNA derived small RNA (tsRNA), ribosomal RNA derived small RNA (rsRNA), large non-coding RNA derived small RNA (lncsRNA), or a messenger RNA derived small RNA (msRNA).

An engineered oligonucleotide can comprise DNA or RNA. In some cases, an engineered oligonucleotide can comprise a plurality of nucleotides. In some cases, an engineered oligonucleotide can comprise an artificial nucleic acid analogue. In some cases, an engineered oligonucleotide can comprise DNA, can comprise cell-free DNA, cDNA, fetal DNA, viral DNA, or maternal DNA. In some cases, an engineered oligonucleotide can comprise an shRNA, or siRNA, an ncRNA mimic, a short-harpin RNA (shRNA), a dicer-dependent siRNA (di-siRNA), an antisense oligonucleotide (ASO), a gapmer, a mixmer, double-stranded RNAs (dsRNA), single stranded RNAi, (ssRNAi), DNA-directed RNA interference (ddRNAi), an RNA activating oligonucleotide (RNAa), or an exon skipping oligonucleotide. In some cases, an engineered oligonucleotide can comprise a completely synthetic miRNA. A completely synthetic miRNA is one that is not derived or based upon an ncRNA. Instead, a completely synthetic miRNA may be based upon an analysis of multiple potential target sequences or may be based upon isolated natural non-coding sequences that are not ncRNAs. One example of a completely synthetic miRNA is E1-001 (Table 4).

A diagnostic test can comprise an imaging procedure, a blood count analysis, a tissue pathology analysis, a biomarker analysis, a biopsy, a magnetic resonance image procedure, a physical examination, a urine test, an ultrasonography procedure, a genetic test, a liver function test, a positron emission tomography procedure, a X-ray, serology, an angiography procedure, an electrocardiography procedure, an endoscopy, a diagnostic polymerase chain reaction test (PCR), a pap smear, a hematocrit test, a skin allergy test, a urine test, a colonoscopy, an enzyme-linked immunosorbent assay (ELISA), microscopy analysis, bone marrow examination, rapid diagnostic test, pregnancy test, organ function test, toxicology test, infectious disease test, bodily fluids test, or any combination thereof.

Conditions or diseases of the present disclosure can include a genetic disorder. A genetic disorder may be an illness caused by abnormalities in genes or chromosomes. Genetic disorders can be grouped into two categories: single gene disorders and multifactorial and polygenic (complex) dis-orders. A single gene disorder can be the result of a single mutated gene. Inheriting a single gene disorder can include but not be limited to autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, Y-linked and mitochondrial inheritance. In some cases, one mutated copy of the gene can be necessary for a person to be affected by an autosomal dominant disorder. Examples of autosomal dominant type of disorder can include but are not limited to Huntington's disease, Neurofibromatosis 1, Marfan Syndrome, Hereditary nonpolyposis colorectal cancer, or Hereditary multiple exostoses. In autosomal recessive disorders, two copies of the gene can be mutated for a subject to be affected by an autosomal recessive disorder. Examples of this type of disorder can include but may not be limited to cystic fibrosis, sickle-cell disease (also partial sickle-cell disease), Tay-Sachs disease, Niemann-Pick disease, or spinal muscular atrophy. X-linked dominant disorders are caused by mutations in genes on the X chromosome such as X-linked hypophosphatemic rickets. Some X-linked dominant conditions such as Rett syndrome, Incontinentia Pigmenti type 2 and Aicardi Syndrome can be fatal. X-linked recessive disorders are also caused by mutations in genes on the X chromosome. Examples of this type of disorder can include but are not limited to Hemophilia A, Duchenne muscular dystrophy, red-green color blindness, muscular dystrophy and Androgenetic alopecia. Y-linked disorders are caused by mutations on the Y chromosome. Examples can include but are not limited to Male Infertility and hypertrichosis pinnae. The genetic disorder of mitochondrial inheritance, also known as maternal inheritance, can apply to genes in mitochondrial DNA such as in Leber's Hereditary Optic Neuropathy.

Genetic disorders may also be complex, multifactorial or polygenic. Polygenic genetic disorders can be associated with the effects of multiple genes in combination with lifestyle and environmental factors. Although complex genetic disorders can cluster in families, they do not have a clear-cut pattern of inheritance. Multifactorial or polygenic disorders can include heart disease, diabetes, asthma, autism, autoimmune diseases such as multiple sclerosis, cancers, ciliopathies, cleft palate, hypertension, inflammatory bowel disease, mental retardation or obesity.

The term “fragment,” as used herein, can be a portion of a sequence, a subset that can be shorter than a full-length sequence. A fragment can be a portion of a gene. A fragment can be a portion of a peptide or protein. A fragment can be a portion of an amino acid sequence. A fragment can be a portion of an oligonucleotide sequence. A fragment can be less than about: 20, 30, 40, 50 amino acids in length. A fragment can be less than about: 2, 5, 10, 20, 30, 40, 50 oligonucleotides in length.

Compositions and methods as described herein include methods of identifying mutations or modifications to a guide strand that may improve therapeutic efficacy through improved knockdown (at least partially or completely) of one or more targets. Sequence modifications to a passenger strand are also described herein. Chemical modifications to one or more both strands are also described herein. Constructs or mimics as described herein may comprise one or more sequence alterations in a guide strand that may curb target recognition toward a preferred mRNA target among a plurality of mRNA targets. Such constructs or mimics may enhance stability, at least partially reduce or eliminate an immune stimulation, improve a pharmacological activity, retain one or more poly-targeting effect, or any combination thereof.

Compositions and methods as described herein can include miR mimics (such as miR-30, miR-29, miR-26, miR-27, miR-101, miR-145, miR-205, miR-338, and miR-375 mimics) having improved stability, safety, and/or activity as compared to a comparable miR (such as miR-30, miR-29, miR-26, miR-27, miR-101, miR-145, miR-205, miR-338, and miR-375).

Mimics can be identified using intelligent design, testing of one or more chemical modification patterns, sequence mutation in passenger strands that can improve mimic complementarity or alter mimic duplex structure, and sequence mutation to the guide strand that can yield benefits in activity. In some cases, a sequence mutation in the guide strand can move beyond use of natural guide sequence to use of mimics. For example, sequence alterations can tailor guide strand activity toward preferred downstream targets, such as clinical targets.

Because miRNAs are grouped in families based on sequence similarity, mutant sequences may be ‘non-natural’ or ‘artificial’ miRNA family members.

The miR-30 family of microRNAs (miRNAs) can include 5 family members in humans (i.e. miR-30a, miR-30b, miR-30c-1, miR-30c-2, miR-30d, and miR-30e). This family can possess tumor suppressor activity in several types of cancers and suppression of fibrosis, scarring or both. For example, miR-30 downregulation can be linked to poor outcome in recurrent head and neck cancer patients. As such, the miR-30 family is an ideal candidate for miRNA replacement therapy. However, developing miR-30 mimics into novel drug candidates can include overcoming pharmacological barriers for therapeutic application such as: (i) inherent metabolic instability being readily degraded by a variety of nucleases found in biological fluids; (ii) contain sequence patterns (e.g. CpG motifs) and structures that may be natural ligands for cell receptors (i.e. TLR family, RIG-I-like receptors, and other RNA sensors) that trigger the innate immune response that can lead to toxicities in vivo; (iii) poor pharmacology in regards to potency and/or efficacy as natural miRNA sequences may not inherently optimized for mimetics; (iv) delivery in vivo to diseased or target tissues; (v) or any combination thereof.

The miR-29 family of microRNAs (miRNAs) can include 4 family members in humans (i.e. miR-29a, miR-29b-1, miR-29b-2, and miR-29c). This family can possess tumor suppressor activity in several types of cancers, antiviral activity, and suppression of fibrosis, scarring or both. For example, miR-29 overexpression can be linked to reduce Hepatitis C Viral abundance in cell culture. As such, the miR-29 family is an ideal candidate for miRNA replacement therapy. However, developing miR-29 mimics into novel drug candidates can include overcoming pharmacological barriers for therapeutic application such as: (i) inherent metabolic instability being readily degraded by a variety of nucleases found in biological fluids; (ii) contain sequence patterns (e.g. CpG motifs) and structures that may be natural ligands for cell receptors (i.e. TLR family, RIG-I-like receptors, and other RNA sensors) that trigger the innate immune response that can lead to toxicities in vivo; (iii) poor pharmacology in regards to potency and/or efficacy as natural miRNA sequences may not inherently optimized for mimetics; (iv) delivery in vivo to diseased or target tissues; (v) or any combination thereof.

In addition, high-degree of chemical modification and/or implementing conventional modification patterns based on siRNA design can often negatively impact miRNA mimic activity by reducing their pleiotropic effects of silencing multiple transcripts. Chemical modifications can alter sequence recognition of otherwise natural downstream targets. While desirable for improving siRNA specificity towards its intended target by reducing its “miRNA-like” off-target effect, it can be undesirable for miRNA mimetics that are developed to deliberately target multiple transcripts.

An oligonucleotide can comprise a sugar modification. An oligonucleotide can comprise a plurality of sugar modifications. A sugar modification can comprise a glucose or derivative thereof. A sugar modification can comprise a ribose or deoxyribose. A sugar modification can comprise a monosaccharide, a disaccharide, a trisaccharide or any combination thereof.

An oligonucleotide can comprise a chemical modification. An oligonucleotide can comprise a plurality of chemical modifications.

UM-SCC-47 cells were plated in 6-well plates and transfected with 15 nM of the indicated engineered miR-30 mimics for 72 hrs. Following treatment, total RNA was collected from the wells and RT-qPCR was performed to determine expression of ITGA6, SERPINE1, and EGFR. HPRT1 served as an endogenous normalization control and expression levels were normalized to negative control (Neg Con) transfections.

Net sum of free energy across all three target sites (NET) and their averaged ΔG (Avg.) is also indicated. Note all artificial guide strands have lower calculated net and averaged free energy for hybridization than natural miR-30-5p family members inferring improved target recognition.

Referring to FIG. 4A-D, this figure shows that engineered oligonucleotides hybridized to form novel miR-30-5p mimics can have equivalent or improved anti-tumor activity in cancer cell lines. FIG. 4A shows UM-SCC-1, UM-SCC-47, and UM-SCC-109 cells were plated in 96-well plates and were transfected with 15 nM mimics using RNAimax agent 6 hours after plating for 5 days. Following treatment, cell viability was assessed by XTT assay. All data represent the mean±SEM relative to cells treated in absence of mimic (designated as 100% viability). All mimics can have unique patterns of chemical modifications and can have one of the modified passenger strands. Mimics are separated based on guide sequence including either miR-30a-5p (Native) or miR-G-30-5p derivatives (Engineered). Anti-tumor activity for each mimic can be statistically (P<0.05) an improvement in reducing cell viability or equivalent to natural miR-30a duplex in each cell line. FIG. 4B shows luciferase activity following treatments in a subline of UM-SCC-1 (UM-SCC-1^(luc)) genetically engineered to overexpress a luciferase reporter containing cancer-relevant miR-30 target sites within its 3′ untranslated region (UTR). UM-SCC-1^(luc) cells were plated in 96-well plates and transfected with 15 nM mimics using RNAimax agent 6 hrs after plating for 3 days before cell lysis and luciferase assay. FIG. 4C displays the anti-tumor activity of native miR-30a and exemplar engineered mimics, M30-043 and M30-046, in additional cell lines with different genetic backgrounds. Indicated cancer cell lines were plated in 96-well plates and were transfected with 25 nM mimics using RNAimax agent 6 hrs after plating for 5 days.

Referring to FIG. 6A-B, this figure shows that modification of mimic sequence and structure can improve stability. FIG. 6A shows engineered mimics; M30-025, M30-040, and M30-044; which have the identical highly stable engineered guide strand, G032-30 (SEQ ID NO: 65) in duplex with passenger strands with sequence and chemical modifications which alter the mimic structure. Indicated is the design schematic towards M30-044 incorporating design features that can further enhance mimic stability. Bases in bold contain 2′-O-methyl modifications, lower case bases have 2′-flouro substitutions, ‘ps’ signifies phosphothioate backbone and (Amino C6) indicates addition of an amino-carbon 6 chain. FIG. 6B shows mimics were incubated in 10% human sera at 37° C. for the indicated lengths of time. Duplex stability at each time point was visualized by denaturing Urea-PAGE. Mimics with enhanced stability can be preferred for use with conjugation-based delivery systems in which the mimic can be directly exposed to nucleases in biological fluids and the delivery does not provide any additional shielding benefit. M30-040 displays superior anti-tumor activity compared to M30-025 or M30-044 as previously demonstrated in FIG. 4B.

Referring to FIG. 7A-C, this figure shows the effect of sequence changes on the mimic structure and activity. FIG. 7A displays the sequences of mimics; M30-033, M30-034, and M30-040. All guide strands have similar chemical modifications (not shown). The same is true for the passenger strands. M30-033 and M30-034 are comprised of the highly stable guide strand G042-30 (SEQ ID NO: 69) which contains the natural miR-30a-5p guide sequence. M30-040 is comprised of G032-30 (SEQ ID NO: 65) which has identical chemical modifications to G042-30 but has an inserted ‘G’ at position 13 (highlighted in grey). M30-033 retains a similar structure as M30-040 (i.e. internal bulge) and M30-034 has the same passenger strand as M30-040. FIG. 7B shows a panel of 6 HNSCC cell lines that were transfected with M30-033, M30-034, M30-040, or a negative control (Neg Con) at 15 nM for 5 days as described above.

All data represent the mean±SEM from three independent experiments. Collectively, M30-040 demonstrates a greater reduction in cell viability and luciferase knockdown activity.

Referring to FIG. 8A-B, this figure shows anti-tumor activity of miR-30 mimic, M30-040, is dependent on guide strand incorporation into RNA-induced Silencing Complex (RISC). FIG. 8A shows the structure of two modifications that can be made to the 5′ terminus of the guide strand. In this experiment, two variants of M30-040 were synthesized with either a 5′-terminal methyl group (5′-OMethyl) or amino-carbon 6 chain (5′-Amino C6) modification of the guide strand, referred to as mimics 5′OMe M30-040 and 5′Amino C6 M30-040, respectively. Chemical modification of the 5′-hydroxyl terminus in guide strands can attenuate activity at least in context to siRNA duplexes by blocking intracellular phosphorylation and subsequent recognition by the RISC effector. FIG. 8B shows UM-SCC-1 and A431 cancer cells treated with each mimic at 15 nM and cell viability was assessed by XTT assay on day 5 as described above.

Sequence and structures are also displayed for engineered mimics M30-046 and M30-048 which are composed of guide strand G130-30 (SEQ ID NO: 87) and G132-30 (SEQ ID NO: 88) respectively and contain an engineered sequence. Its chemical modification pattern was designed to retain poly-targeting activity of downstream transcripts. Indicated is the design schematic towards M30-048 incorporating an accumulation of features leading to improved activity, including a 3′ terminal modification pattern and mimic bulge structure. Bases in bold contain 2′-O-Methyl modifications, lower case bases have 2′-fluoro substitutions, ‘ps’ signifies phosphothioate backbone and (Amino C6) indicates addition of an amino-carbon 6 chain. FIG. 9B displays anti-tumor activity in a panel of cancer cell lines transfected with the indicated mimics or a negative control (Neg Con) at 15 nM for 5 days.

Compared to unmodified, natural miR-30a, M30-043 has improved activity on cell viability at 7.5 nM in a panel of 7 HNSCC cell lines in vitro. Statistical significance (P<0.05) compared to miR-30a treatment is indicated. FIG. 10B shows luciferase activity following 15 nM treatments in a subline of UM-SCC-1 (UM-SCC-1^(luc)) genetically engineered to overexpress a luciferase reporter containing miR-30 target sites within its 3′UTR.

Levels of TNF-α (FIG. 11A) and IFN-α (FIG. 11B) in supernatant media were quantified by ELISA. Poly (dA:dT) oligonucleotide served as a positive control for immunostimultation. Transfection with a non-chemically modified RNA duplex (Non-mod) demonstrated potential of mimic immunostimulation. Cells treated in the absence of mimic served to establish baseline.

Referring to FIG. 12A-D, this figure displays sensitization of cancer cells to approved treatments, cisplatin and cetuximab, when treated with engineered mimic, M30-040, in combination in vitro. FIG. 12A shows UM-SCC-1 and -46 cancer cells were cultured in the presence of escalating micro-doses of cisplatin for ≥3 months to create sublines resistant to cisplatin. Dose response curves evaluating cytotoxicity demonstrated enhanced resistance to cisplatin compared to parental cell lines.

FIG. 14A shows Female SCID mice were implanted with UM-SCC-1^(Luc) subline in floor-of-mouth on the left side of their oral cavity. 14 days after tumor implantation, bioluminescence was monitored in live animals using In Vivo Imaging System (IVIS) by dosing with D-luciferin at 150 mg/kg via IP injection. Engineered mimic, M30-048, or a Negative control mimic (Neg. Con.) was formulated into an Atelocollagen gel using the AteloGene® local kit (koken). Animals were treated with a single treatment of 1.5 mg/kg or 3 mg/kg of M30-048 or 3 mg/kg of Neg. Con mimic and silencing of luciferase was monitored for 96 hrs.

Referring to FIG. 15 , this figure shows natural miR-29 guide strand sequences and examples of engineered family members. Shown are the sequences of the natural miR-29 family members found in human (i.e. miR-29a-c-3p). Sequence variation between the different family members as compared to miR-29c-3p are highlighted in grey. Examples of non-natural sequences comprising subsets of engineered family members can include (i) combining the natural differences between miR-29a-3p and miR-29b-3p into hybrid sequences (Hybrid); (ii) A-to-G and/or U-to-G base mutations at positions 14 and/or 15, respectively (Mutation); (iii) guanidine base insertion at position 15 (Insert.); and (iv) sequences combining mutation with the base insertion into miR-29b-3p (Mut.+Insert.) or hybrid sequence (Hybrid+Mut.+Insert.).

Referring to FIG. 16 , this figure shows a schematic visualization of a human host cell gene that is an epigenetic modifier and is involved cancer and reactivation of latent HIV virus. Shown is an illustration of the TET1 mRNA including its coding domain and three experimentally-validated miR-29 target sites (indicated in grey) within its 3′UTR. Hybridization between natural miR-29b-3p and the TET1 target sites, as well as calculated free energy (ΔG) for miR-29-3p and the indicated artificial guide strands were calculated using the software RNAhybrid 2.2 (https.//bibiserv.cebitec.uni-bielefeld.de/mahybrid). Net sum of free energy across all three target sites (NET) and their averaged ΔG (Avg.) is also indicated. Note all artificial guide strands can have lower calculated net and averaged free energy for hybridization than natural miR-29b-3p inferring improved target recognition. As with the NEF example depicted in FIG. 22 , the engineered miR-29 guide strands depicted in FIG. 16 can be used to bind and inhibit an mRNA expressing a TET1 host protein with a lower predicted free energy (ΔG), a greater specificity, and greater complementarity, than corresponding natural miRNA sequences lacking the modifications described herein. Since TET1 is important in many disorders included Cancer and viral infections, this demonstrates that the engineered miR-29 guide strands may have improved properties as therapeutic agents by improving targeting of TET1.

Referring to FIG. 17 this figure shows miR-29 mimics can have equivalent or greater knockdown activity compared to native miR-29b-1. Luciferase activity of a stable subline of HEK cells ( ) genetically engineered to overexpress a luciferase reporter containing a miR-29 target site within its 3′UTR. HEK^(luc) cells were plated in 96-well plates and transfected with 15 nM mimics using RNAimax agent 6 hrs after plating for 3 days before cell lysis and luciferase assay.

Duplex complementarity was enhanced via sequence alterations in M29-012. In some cases, chemical modifications can be performed to any of the guide strands. FIG. 18B shows that reduction in duplex bulges in combination with the chemical modification pattern of the passenger strand contributes to improving duplex stability in absence of additional chemical modification of the guide strand. 5 μM of miR-29b-1 and the miR-29 mimics were incubated in 10% human sera at 37° C. for the indicated lengths of time. Duplex stability was visualized at the indicated time points by denaturing Urea-PAGE.

Referring to FIG. 19A-B, this figure shows chemical modifications can improve miR-29 mimic stability. FIG. 19A shows sequence and structure of exemplar engineered miR-29 mimics with chemical modifications to stabilize them to human nucleases. FIG. 19B shows miR-29 mimics were incubated in 10% human sera at 37° C. for the indicated lengths of time. Duplex stability at each time point was visualized by denaturing Urea-PAGE. Time points without bands or with prominent smearing are either missing samples time points or user loading error, respectively.

Referring to FIG. 20A-C, this figure shows passenger strand modification that can improve native miR-29a-3p and miR-29b-3p knockdown activity. FIG. 20A shows sequence comparison of native miR-29a duplex with mimics M29-023 and M29-002, which differ by passenger strand composition. All three duplexes contain unmodified, natural miR-29a-3p guide strand sequence. Bases in bold contain 2′-O-methyl. Amino-carbon 6 chain (Amino C6) modification of the 5′ terminus for the indicated passenger strands is also shown. FIG. 20B shows sequence comparison of native miR-29b duplex with mimics M29-007 and M29-008. All three duplexes contain the same unmodified, natural miR-29b-3p guide strand sequence.

All data represent the mean±SEM from three independent experiments where cells were assayed 72 hours post-transfection. The knockdown activity of mimics containing either native miR-29a-3p (29a-3p) or miR-29b-3p (29b-3p) can be improved over natural miR-29a and miR-29b duplexes by hybridizing guide strands with modified passenger strands.

Referring to FIG. 21 , this figure displays reductions in innate immunostimulation for engineered miR-29 mimics. Human Peripheral Blood Mononuclear Cells (PBMCs) (˜2×10⁵ cells) were plated in round bottom 96 well plates and transfected at 133 nM concentrations of the indicated mimics for 48 hours with RNAiMAX reagent. Levels of IFN-α and TNF-α in supernatant were quantified by ELISA. Poly(dA:dT) oligonucleotide and non-modified RNA duplex with known strong stimulatory effects (Pos Con) served as positive controls for immunostimulation. Transfection with non-chemically modified miR-29a and miR-29b duplexes (Non-mod) served as comparative controls for the indicated example mimics containing chemical modifications. Cells treated in in absence of mimic served to establish baseline.

Referring to FIG. 22A-B, this figure shows a schematic visualization of an HIV viral RNA transcript that codes for a viral protein (NEF) and can be an antiviral target for HIV. FIG. 22A shows free energy (ΔG) and hybridization between natural miR-29b-3p with its cognate target site in the viral transcript of NEF was calculated using the software RNAhybrid 2.2 (https://bibiserv.cebitec.uni-bielefeld.de/mahybrid). For example, artificial miR-29 guide strands consisting of hybrid sequence (G003-29) and/or other non-natural changes (G004-29, G020-29, G027-29, and G031-29) can have lower predicted free energy (ΔG) and greater complementarity inferring improved target recognition. Improved target recognition, as demonstrated herein, can result in a decrease in a Gibbs Free Energy of binding of an engineered oligonucleotide for a target RNA, can result in an increase specificity of the engineered oligonucleotide for the target RNA, among a plurality of other RNA sequences, or a combination of these features. Accordingly, the engineered miR-29 guide strands depicted in FIG. 22A can be used to bind and inhibit an mRNA expressing a NEF viral protein with a lower predicted free energy (ΔG), a greater specificity, and greater complementarity, than corresponding natural miRNA sequences lacking the modifications described herein. Thus, the engineered miR-29 guide strands can display a potent anti-viral activity against HIV viruses or other virus displaying a NEF viral protein as demonstrated in FIG. 22B. FIG. 22C shows 3*10⁴ CD4+ human t-cells were transfected with 100 nM of either control, M29-012 or M29-028 mimic. 24 hours post-transfection cells were infected with pNL4-HIV, which contains a GFP reporter cloned nest to the NEF gene.

Cells were collected and total RNA was purified by directzol kits. Following reverse transcription relative expression of miR-29 target genes Tet3 (FIG. 23A), Cyclin T1 (FIG. 23B), and DNMT3A (FIG. 23C) was assessed by quantitative RT-PCR. Values represent the mean of three biological replicates and error bars represent SEM. * denotes p-value<0.05 by 2 tailed student's T-test. In all cases the engineered mimics of miR-29 have improved knockdown of targeted mRNA than the natural miRNAs.

Net sum of free energy across all three target sites (NET) and their averaged ΔG (Avg.) is also indicated. FIG. 25C demonstrates the protective effects of exemplar engineered miR-29 (M29-028) and miR-30 mimics against (M30-043 and M30-48) SARS-CoV-2-induced cell death. 5×10³ Vero cells were plated in 29 well plates and 6 hrs after plating transfected with 25 nM control, M29-028, M30-043 or M30-048 mimics and then infected with SARS-CoV-2 (MOI 0.03) 24 hours later. After another 72 hours, cells were assayed for viral-induced cytopathic effect using viral toxglo assay (Promega). Pre-treatment with either M29-028, M30-43 or M30-048 resulted in ˜30-40% less viral-induced cell death. miR-29 guide sequences, for example SEQ. ID. NO. 102 or SEQ. ID.

ID. NOs. 12, 13, 102, 103, 112, 115, 119, 117, 105, 110, 109, 100, can have antiviral activity against the HCV Genotype 1.

The antiviral properties of the miR-29, miR-30, or miR-26 families can also be conserved amongst other RNA-based viruses that contain target sites within their genome or depend on similar host gene transcripts (e.g. TET1, TET2, TET3, etc.). Based on seed sequence complementarity, 26 and 32 candidate target sites in the genomic transcripts of SARS and SARS-CoV-2 coronavirus, respectively. Calculated free energy (ΔG) for three example targeted sites indicate that many of the artificial family member can have improved binding potential over native miR-29a-3p, miR-29b-3p, or miR-30a-5p in both SARS (FIG. 24 ) and SARS-CoV-2 (FIG. 25 ) genomic transcript. Similarly, artificial family members also demonstrated improved calculated binding across three candidate target sites in Hepatitis C virus (HCV) genome (FIG. 26 ). The mimics, including artificial family members, may have broad acting antiviral properties at treating or preventing infection of RNA-based viruses.

The computer system 101 can be an electronic device of a user or a computer system that is remotely located with respect to the electronic device. The electronic device can be a mobile electronic device.

The computer system 101 includes a central processing unit (CPU, also “processor” and “computer processor” herein) 105, which can be a single core or multi core processor, or a plurality of processors for parallel processing. The computer system 101 also includes memory or memory location 110 (e.g., random-access memory, read-only memory, flash memory), electronic storage unit 115 (e.g., hard disk), communication interface 120 (e.g., network adapter) for communicating with one or more other systems, and peripheral devices 125, such as cache, other memory, data storage and/or electronic display adapters. The memory 110, storage unit 115, interface 120 and peripheral devices 125 are in communication with the CPU 105 through a communication bus (solid lines), such as a motherboard. The storage unit 115 can be a data storage unit (or data repository) for storing data. The computer system 101 can be operatively coupled to a computer network (“network”) 130 with the aid of the communication interface 120. The network 130 can be the Internet, an internet and/or extranet, or an intranet and/or extranet that is in communication with the Internet. The network 130 in some cases is a telecommunication and/or data network. The network 130 can include one or more computer servers, which can enable distributed computing, such as cloud computing. The network 130, in some cases with the aid of the computer system 101, can implement a peer-to-peer network, which can enable devices coupled to the computer system 101 to behave as a client or a server.

The CPU 105 can execute a sequence of machine-readable instructions, which can be embodied in a program or software. The instructions can be stored in a memory location, such as the memory 110. The instructions can be directed to the CPU 105, which can subsequently program or otherwise configure the CPU 105 to implement methods of the present disclosure. Examples of operations performed by the CPU 105 can include fetch, decode, execute, and writeback.

The CPU 105 can be part of a circuit, such as an integrated circuit. One or more other components of the system 101 can be included in the circuit. In some cases, the circuit is an application specific integrated circuit (ASIC).

The storage unit 115 can store files, such as drivers, libraries and saved programs. The storage unit 115 can store user data, e.g., user preferences and user programs. The computer system 101 in some cases can include one or more additional data storage units that are external to the computer system 101, such as located on a remote server that is in communication with the computer system 101 through an intranet or the Internet.

The computer system 101 can communicate with one or more remote computer systems through the network 130. For instance, the computer system 101 can communicate with a remote computer system of a user. Examples of remote computer systems include personal computers (e.g., portable PC), slate or tablet PC's (e.g., Apple® iPad, Samsung® Galaxy Tab), telephones, Smart phones (e.g., Apple® iPhone, Android-enabled device, Blackberry®), or personal digital assistants. The user can access the computer system 101 via the network 130.

Methods as described herein can be implemented by way of machine (e.g., computer processor) executable code stored on an electronic storage location of the computer system 101, such as, for example, on the memory 110 or electronic storage unit 115. The machine executable or machine-readable code can be provided in the form of software. During use, the code can be executed by the processor 105. In some cases, the code can be retrieved from the storage unit 1115 and stored on the memory 110 for ready access by the processor 105. In some situations, the electronic storage unit 115 can be precluded, and machine-executable instructions are stored on memory 110.

The code can be pre-compiled and configured for use with a machine having a processer adapted to execute the code or can be compiled during runtime. The code can be supplied in a programming language that can be selected to enable the code to execute in a pre-compiled or as-compiled fashion.

Aspects of the systems and methods provided herein, such as the computer system 101, can be embodied in programming. Various aspects of the technology can be thought of as “products” or “articles of manufacture” typically in the form of machine (or processor) executable code and/or associated data that is carried on or embodied in a type of machine readable medium. Machine-executable code can be stored on an electronic storage unit, such as memory (e.g., read-only memory, random-access memory, flash memory) or a hard disk. “Storage” type media can include any or all of the tangible memory of the computers, processors or the like, or associated modules thereof, such as various semiconductor memories, tape drives, disk drives and the like, which can provide non-transitory storage at any time for the software programming. All or portions of the software can at times be communicated through the Internet or various other telecommunication networks. Such communications, for example, can enable loading of the software from one computer or processor into another, for example, from a management server or host computer into the computer platform of an application server. Thus, another type of media that can bear the software elements includes optical, electrical and electromagnetic waves, such as used across physical interfaces between local devices, through wired and optical landline networks and over various air-links. The physical elements that carry such waves, such as wired or wireless links, optical links or the like, also can be considered as media bearing the software. As used herein, unless restricted to non-transitory, tangible “storage” media, terms such as computer or machine “readable medium” refer to any medium that participates in providing instructions to a processor for execution.

Hence, a machine readable medium, such as computer-executable code, can take many forms, including but not limited to, a tangible storage medium, a carrier wave medium or physical transmission medium. Non-volatile storage media include, for example, optical or magnetic disks, such as any of the storage devices in any computer(s) or the like, such as can be used to implement the databases, etc. shown in the drawings. Volatile storage media include dynamic memory, such as main memory of such a computer platform. Tangible transmission media include coaxial cables; copper wire and fiber optics, including the wires that comprise a bus within a computer system. Carrier-wave transmission media can take the form of electric or electromagnetic signals, or acoustic or light waves such as those generated during radio frequency (RF) and infrared (IR) data communications. Common forms of computer-readable media therefore include for example: a floppy disk, a flexible disk, hard disk, magnetic tape, any other magnetic medium, a CD-ROM, DVD or DVD-ROM, any other optical medium, punch cards paper tape, any other physical storage medium with patterns of holes, a RAM, a ROM, a PROM and EPROM, a FLASH-EPROM, any other memory chip or cartridge, a carrier wave transporting data or instructions, cables or links transporting such a carrier wave, or any other medium from which a computer can read programming code and/or data. Many of these forms of computer readable media can be involved in carrying one or more sequences of one or more instructions to a processor for execution.

The computer system 101 can include or be in communication with an electronic display 135 that comprises a user interface (UI) 140 for providing, for example, one or more results (immediate results or archived results from a previous method), one or more user inputs, a reference value or derivative thereof from a library or database, or any combination thereof. Examples of UI's include, without limitation, a graphical user interface (GUI) and web-based user interface.

Methods and systems of the present disclosure can be implemented by way of one or more algorithms. An algorithm can be implemented by way of software upon execution by the central processing unit 105. The algorithm can, for example, determine optimized constructs via supervised learning to optimize therapeutic efficacy, stability, or other attribute of one or more constructs.
